It's the internet, I've been doing this since I was 11, and all I can say is expect people to be greedy selfish petty small minded losers. When I join a PUG it's to get the mission done, that's it, that's all. I roll greed on everything, I get zero loot, I don't care, I'll never play with any of these idiots again. If some of them aren't idiots, that's cool, and opens up potential friends, guildies, or allies... but don't expect it. I make plenty of cash and loot when I'm teamed up with friends, guildies, or just plain solo, so I don't care what happens in the PUG so long as I get a mission complete at the end of it. You might not like it but this is the internet, if you expect anything different you're going to be very unhappy and likely rage on forums a lot... Hope for the best, but expect the worse, especially online.
